Light, ergonomically designed micropipettes prevent hands from becoming tired during repetitive operations. They are equipped with a microprocessor controlled stepper motor for dispensing precise volumes with the help of a piston and an optical coupler that monitors the position of the piston to guarantee that the movement is repeated with precision every time. Wide LCD screen and convenient interface Memory is capable of storing up to nine configurations of functional parameters Permanent self-test programme ensures the precision of the pipetted volumes and battery dependence Auto-calibration function
